SSH Login freezes after successful authentication

We are currently experiencing and issue where when we log into our SCO
Unix server (any user) it hangs as soon as you put in a successful
password. This all occurred after we had to reboot the server.

If a wrong password is input, it does deny access and lets you become
aware of your failure, but on success... its just frozen, before you
even get a shell prompt.

This is what we get:
root@192.168.12.240's password:
[]

Please provide the version of Unix and the version of sshd it is running,
and also the version of the ssh client that is attempting to log in.

Please also try to run ssh with the -v option.

Looks like a tset prompt, waiting for the user to enter the terminal
type.

Try debugging statements in your .profile or .login, depending on the
shell.

Are you sure? This happens to any user who tries to log on after a
certain amount of users have logged on. Once a user logs on after
that, their session is frozen they can't type anything, they must exit
the terminal. A simple ps -ef | grep sshd | wc showed the number of
logged on users increasing. We had it up to about 30 users at one
point when there were only 4 physical machines logged on and using the
server. I added in the '[]' to represent the blinking cursor :P.

How would I enable debugging for all users? Is there an easy way to do
this?

Uh, you're running OpenBSD software on OSR 6.0.0? Why, since OSR 6.0.0
already provides ssh binaries? You didn't tell us what the ssh client
is, nor do you report trying to use the verbose option.

I did NOT ask for the first line in /etc/ssh/sshd_config, did I?
I asked for the version of sshd. On OSR 6, I'd expect:
OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007
